In order to avoid when normal driving, driver's cabin 7 follows curved support frame 3 around the hinged secondary swing with intermediate longitudinal girder 21, when described slide block 111 be resisted against the first chute 2211 foremost time, the first described spring 15 is in compressive state.
As shown in Figure 10 and Figure 11, described rear anti-crash frame 4 is installed on the rear end on chassis 2, including first cross bar the 41, second cross bar 42, first connecting rod 43, Angle Pin the 44, second slip ring the 45, second spring 46 and skidding mechanism 47. As shown in figure 13, first described cross bar the 41, second cross bar 42 and be respectively arranged at the first connecting rod 43 at the first cross bar 41 and the second cross bar 42 two ends and form tower structure, and one end of described first connecting rod 43 protrudes from the second cross bar 42, described first cross bar 41 and the second vertical intermediate longitudinal girder 21 with described chassis 2 of cross bar 42, the two ends of described first cross bar 41 are separately installed with trailing wheel 9.One end protruding from the second cross bar 42 of described first connecting rod 43 is all tiltedly installed with Angle Pin 44, it is preferred that angle of inclination is 45 °. As shown in figure 14, the dumbbell shaped that described Angle Pin 44 is little in the big mid diameter of two ends diameter, and the little position of described mid diameter is provided with between one end that the second slip ring 45, described second slip ring 45 and the superposed diameter of Angle Pin 44 are big and is provided with the second spring 46. Described second slip ring 45 is provided with hinge hole. As shown in Figure 12 and Figure 13, described skidding mechanism 47 includes leading truck 471, second connecting rod 472 and friction and pedals 473. The two ends of described leading truck 471 are respectively arranged with the second guide post 4711, the second described guide post 4711 both passes through one end of the second fairlead 411 and described second connecting rod 472 that are arranged at the first cross bar 41 and is hinged, described second guide post 4711 can slide along the second fairlead 411, the other end of described second connecting rod 472 and described friction pedal the middle part of 473 to hinged, described friction is pedaled one end of 473 and is hinged with the second described cross bar 42, and described friction is pedaled the suspension end of 473 and is provided with the friction pad that the high-abrasive materials such as rubber are made.
As shown in figure 11, bottom described driver's cabin 7, the position of close Angle Pin 44 has the inclined-plane 71 identical with Angle Pin 44 angle of inclination.
The annexation on described rear anti-crash frame 4 and chassis 2 as shown in Figure 13 and Figure 14, is hinged relationship between described rear anti-crash frame 4 and chassis 2, and namely the hinge hole by being arranged on the second slip ring 45 is hinged with the jointed shaft being arranged at rear cross beam 24 two ends.
Based on above-mentioned design, when the rear portion of vehicle collides, leading truck 471 first with front vehicle to contacting, the second guide post 4711 being now arranged on leading truck 471 can move along the second fairlead 411 to driver's cabin 7 direction, then passing through second connecting rod 472 promotes friction to pedal 473 and rotate down around the hinged pair between itself and the second cross bar 42, until 473 and earth surface are pedaled in friction, thus playing braking action, for slighter collision, can absorb owing to rear car clashes into the deflection caused by skidding mechanism 47, the driver and crew in driver's cabin 7 are avoided to be impacted. for more serious collision, when skidding mechanism 47 is not enough to absorb and clashes into, due to rear car, the deflection caused, now it is adjacent to completely between leading truck 471 and the first cross bar 41, under the effect of impact force, whole rear anti-crash frame 4 can move forward, owing to being provided with Angle Pin 44 between chassis 2 and rear anti-crash frame 4, and be hinged relationship between described chassis 2 and rear anti-crash frame 4, when rear anti-crash frame 4 moves forward, the rear cross beam 24 on the described chassis 2 being hinged with the second slip ring 45 can passive moving upward along Angle Pin 44, second spring 46 is compressed, and then drive chassis 2 and driver's cabin thereon 7 to move upward along Angle Pin 44, driver's cabin 7 is lifted, thus when collision free occurs, impact force directly acts on driver and crew.
Weak owing to rear anti-crash frame 4 and chassis 2 being attached comparison by hinged pair merely, when occurring particularly in collision, under the effect of huge impact force, hinged pair is susceptible to fracture, generation in order to avoid above-mentioned situation, being provided with buffer gear 6 between described chassis 2 and rear anti-crash frame 4, described buffer gear 6 is two, and symmetrical about intermediate longitudinal girder 21. As shown in figure 15, described buffer gear 6 includes the 3rd guide post the 61, the 3rd fairlead 62 and the 3rd spring 63, the 3rd described guide post 61 and the first cross bar 41 of rear anti-crash frame 4 are hinged, the rear cross beam 24 on described 3rd fairlead 62 and chassis 2 is hinged, described 3rd guide post 61 can slide in the 3rd fairlead 62, and the outside of described 3rd guide post 61 and the 3rd fairlead 62 is cased with the 3rd spring 63.So, when a collision occurs, the rear cross beam 24 on chassis 2 can drive buffer gear 6 to be rotated up with the hinged pair of the first cross bar 41 around it, simultaneously the existence of the 3rd spring 63, it is possible to plays the effect of buffering.
